+(The above lines make this file accessible through :INFO.  Please leave
+them alone.)
+
+These guidelines about where to send which system-wide messages are the
+consensus of opinion of AI and LCS staff, based on years of experience of
+what kinds of messages people send.  Since these staff people are the
+official MIT users of the computers the messages are sent on, everyone who
+sends a system-wide message -- this means YOU -- should follow the
+guidelines.
+
+System-wide messages fall into two categories: System Messages (sysmsgs)
+and Bulletin Board messages (BBoard).  Sysmsgs can be split into further
+categories according to which computers should receive them.
+
+The sysmsg addresses are for messages of general interest only.  These
+include official Lab announcments, listings of Lab seminars, machine
+maintenance schedules, announcements about the Dover, questions of GENERAL
+interest to computer scientists, and similar things.
+
+All other messages intended for system-wide distribution, including
+requests for information, job offers, housing searches, political
+pronouncements, and other material of that nature, should go to the BBoard.
+Messages relating to "personal profit", such as messages offering household
+goods for sale, are frowned upon by the DCA (they run the ARPANET), but if
+you can't restrain yourself from sending such a message, it should also go
+to the BBoard.
+
+Good relations among users of the Labs' computers rely in part on people
+not being inundated with junk mail; system messages which go to
+inappropriate addresses are junk mail.  Please think before you send your
+system-wide messages, and use consideration and discretion in addressing
+them.
+
+What follows is a list of addresses with descriptions of which machines
+they direct messages to.  Send your message to the correct address at any
+ITS, e.g. *MAC@ML, to make it go where you want it to.  Send to the address
+at only ONE ITS (which one doesn't matter -- *MIT@MC = *MIT@AI, and so
+forth), or people will see many duplicates of your message, which can only
+make them angry at you.
+
+    *MAC	The right address for reaching all AI and LCS members who
+		use computers.  Use this, not *ITS or *TENS, for things
+		like Lab seminar info.  This list now includes all four
+		ITSs, OZ, XX, HT-VAX, and the RTS VAX; as the
+		Labs acquire more machines that can receive mail, they will
+		be added to *MAC.
+
+    *MIT	Everywhere at MIT that can hear -- all of *MAC, plus CIPG,
+		DSPG, EE, Multics, also an address at CMU so that lonely
+		former MIT people out there can see what's going on.  (As
+		more mail-server machines are added to the ChaosNet, they
+		will join this list.)  Use this address for messages of
+		general interest to the MIT community, like Dover info
+		(which even Multics can use).
+
+    BBOARD	These are the same address; use either.  Unless your
+    *BBOARD	message is important to most of the people gathered in one
+		of the above or below addresses (see the beginning of this
+		file for specifications of "important"), send it here.
+		This list includes all the *MIT sites, but users can choose
+		whether to read these messages.
+
+Unless your message relates to a particular machine or kind of machine (or
+program on same), you probably want to use one of the above lists.  The
+rest, which follow, are more special-purpose; send sysmsgs to them only
+when your message clearly should go to only their constituent machines.
+
+    *		On any ITS, becomes a sysmsg on just that machine.
+
+    *AI, *MC	Becomes a sysmsg on just that particular ITS.  Use these or
+    *ML, *DM	* (above) for a sysmsg affecting only one ITS, like disk
+		maintenance.
+
+    *ITS	Goes only to the four ITSs, listed above.  Use if your
+		message relates only to ITSs, for instance a new ITS
+		version; otherwise you probably want *MAC or *MIT.
+
+    *VX		Goes just to the RTS VAX.
+
+    *HT         Goes just to HTVAX.
+
+    *XX		These are the same address.
+    Forum@XX	They go just to XX, the LCS Twenex.
+
+    *EE		These are the same address.
+    Forum@EE	They go just to the EECS Dept. Twenex.
+
+    *OZ		These are the same address.  They go just to OZ, the AI Lab
+    System@OZ	Twenex, and are for important (see above) msgs only.
+
+    Forum@OZ	For BBoard msgs to OZ.
+
+    *TENS	The most unlikely address.  This goes to the four ITSs, XX,
+		OZ, and EE, but NOT the Vaxen or the RTS 11.  Unless your
+		message relates only to PDP-10s and DEC-20s, you probably
+		want *MAC or *MIT.
